Fact Check: What "No Tax on Overtime" Actually Means

26 U.S.C. § 225 grants a federal income-tax deduction (not an exemption) on the qualifying overtime premium portion only. The article's opening line uses the same phrasing — "'No tax on overtime' is not no tax." The qualifying portion is the 0.5× extra above the regular rate that distinguishes time-and-a-half from straight-time pay.

§ 225(c) defines "qualified overtime compensation" as overtime "in excess of the regular rate" — that is, the 0.5× extra portion only, not the full 1.5× check. The IRS-finalized 2026 Form W-2 Box 12 code TT reports only the qualifying premium amount.

IRS finalized the 2026 Form W-2 on January 12, 2026 with new Box 12 code TT for "Total amount of qualified overtime compensation." The statutory basis for the reporting requirement is 26 U.S.C. § 6051(a)(19). 2025 W-2 reporting is optional (per Notice 2025-69); 2026 reporting is mandatory.

§ 225(c) restricts qualifying overtime to overtime "required under section 7 of the Fair Labor Standards Act" — the federal weekly 40-hour rule only. State-only overtime (California's daily 8-hour rule, Washington's daily standard, etc.) is not federally required and therefore does not qualify for the deduction or for Box 12 code TT reporting.

California's overtime after 8 hours/day, double-time after 12 hours/day, and 7th-consecutive-day premium are all state-only requirements outside FLSA § 7. The article calls this out as one of the most expensive misconceptions — including California daily OT in Box 12 code TT inflates the federal deduction on every CA worker's W-2.

FLSA § 13 exempts executive, administrative, professional, outside-sales, and certain computer employees from overtime requirements — these are commonly described as "salaried" employees in business practice. § 225(c)'s "required under section 7 of the FLSA" language excludes any voluntary employer-policy overtime paid to exempt employees. The W-2's exempt-status flag will surface this category of mis-reporting first under any IRS review.

Box 12 code TT is the premium portion only (0.5× the regular rate × overtime hours), not the full time-and-a-half check. Reporting the full 1.5× amount triples the qualifying amount on every employee's W-2. The IRS-finalized 2026 W-2 guidance is explicit on the 0.5×-only scope. § 6721 penalty is $310 per incorrect information return, capped at $3,783,000 per filer per year (2026 figures).

IRS Notice 2025-69 makes 2025 W-2 / 1099 reporting of the OBBB overtime deduction optional. Notice 2025-62 provides penalty relief for 2025 information-reporting non-disclosure. The article's playbook recommends most employers skip 2025 voluntary disclosure because calculating qualified overtime compensation from pay stubs is straightforward for employees who care, and voluntary disclosure introduces inquiry risk if the figures are later judged wrong.

Four states confirmed: California (SB 711 sets state IRC conformity date to January 1, 2025, before the OBBB enactment date — the deduction falls outside California's tax base), New York (IT-225 add-back codes require the federal deduction to be added back to state taxable income), Illinois (Office of Management and Budget projects $267M revenue protection), Colorado (HB 25-1296, federal-deduction add-back effective January 1, 2026).

California (SB 711 — conformity date precedes OBBB enactment, so § 225 is structurally outside the CA tax base), New York (IT-225 add-back codes), Illinois (OMB projects $267M revenue protection), Colorado (HB 25-1296, effective January 1, 2026). Each state requires the federal § 225 deduction to be added back to state taxable income.

§ 225(b) caps the deduction at $12,500 (single) / $25,000 (joint). Phase-out: $100 per $1,000 of MAGI above $150,000 (single) / $300,000 (joint); full phase-out at $275,000 / $550,000. § 225(g) sunsets the deduction for tax years beginning after December 31, 2028.

§ 225 is a federal income-tax deduction; FICA (Social Security and Medicare) is a separate tax base that the deduction does not reach. The article makes the same point explicitly in its "5 Most Expensive Misconceptions" framing.

IRS did not update Circular E withholding tables for the OBBB overtime deduction. Employees see the benefit at tax filing when the deduction lands on Schedule 1-A; paychecks during the year reflect unchanged withholding.

The three conditions — overtime required under FLSA § 7 ("federal overtime"), the 0.5× extra portion only ("extra-half only"), and FLSA-nonexempt status of the employee ("hourly only" in plain English) — together produce the qualifying scope under § 225(c). Pay codes that fail any of the three are excluded from Box 12 code TT. The asymmetry of the close (deduction shrinks vs penalty doesn't) anchors to § 6721's $310-per-form / $3.78M-annual penalty cap.
